Well I went out to the range yesterday and had some interesting results.

The 58 gr VMax with 26.5 Varget averaged 2651 fps and the 75 gr VMax with the same 26.5 Varget averaged 2745 fps. I would have thought the heavier bullet would have been slower. This leads me to think Varget might be a bit slow burning for the lighter 58 grainers. Although, I think I may want to stay with the Varget since despite my shooting ability they are all trying to fly in the same hole. Next I'll work up some 87g VMax loads with 4895 and Varget and see what happens.

Well... I think what I really need is another upper with a 24 inch barrel.
